Chanelle Hayes is pregnant with her second child, after fears her extreme weight gain had left her infertile

Chanelle Hayes is pregnant with her second child.

The 29-year-old television personality, who has six-year-old son Blakely with her former partner Matthew Bates, has confirmed she is expecting a baby with her boyfriend Ryan Oates, although the exciting news has come as a "surprise" to her after fears her extreme weight gain had left her infertile.

A spokesperson for the golden-haired beauty told The Sun Online: "I'm delighted to confirm that Chanelle Hayes is pregnant with her second child.

"Although the news came as some surprise, Chanelle, her partner Ryan and son Blakely are incredibly excited to welcome the new arrival later this year."

The former 'Big Brother' contestant - who took part in the reality show in 2007 aged 19 years old - has made it known she has always been desperate to expand her brood.

Speaking earlier this year, she said: "I want to have more children - not right now obviously because it's basically impossible - but it's something I want."

Although Chanelle has been eager to give her child another sibling she has previously been told she wouldn't be able to fall pregnant naturally until she dropped a few dress sizes because her love of sugary snacks has interfered with her menstrual cycle.

She explained: "It's absolutely terrifying. I think because I've been so extreme with the way I've been doing things, when I do put weight on, it goes on a lot quicker."

Chanelle was also told she was on the cusp of Type 2 diabetes - a lifelong condition that causes a person's blood sugar level to become too high - and doctors will continue to monitor her waistline and symptoms until she's managed to lose weight.

She said: "They've kind of said if you get any tingling in your limbs or lower limbs and stuff like that. They are keeping an eye on things. They want to do measurements."
